WASHING AND BLEACHING- COMPOUND.

No Drawing.

To all whom it may concern:

Be it known that 1, JOHN Bannmc'rox, a citizen of the United States, residing at Brooklyn, in the county of Kings, State of New York, have invented a new and useful Washing and Bleaching Compound, of which the following is a specification.

My invention relates to a new and useful washing and bleaching compound and has for its object to precipitate the lime, magnesia and other hardness in water and to cleanse and bleach cotton material without rubbing.

The compound consists of a mixture of perborate of sodium, borax, and a neutral product (not alkaline) such as mono-phosphate of sodium.

As an example of the proportions which I may use, and which has been found in practice to give satisfactory results, I combine 20% of perborate of sodium, 40% of bor and 40%Wof s dium.

t er proportions may [E employed, but the above have given the best results.

Jhemihndmsniihiih iRlQii j to Place 5 ounces of the compound in a wash boiler of cold Water and add about 3 ounces of shaved soap after which the soiled cotton clothes are immersed. This is brought to a boil and boiled about twenty minutes after ghicih the clothes are removed, rinsed and Copies of this patent may be obtained for Specification of Letters Patent.

Patented Nov. 16, 1915.

By the use of the neutral product (not alkaline) mono-phosphate of sodium, the lime ma esia etc. in hard water, when boiled, wil c emicil, ,Lpmc p ated so med and permits the action of the other compounds to become more easily effective, the borax cleaning, and the dsodium perborate bleaching, the cotton goo s.

In this manner, the cleaning and bleaching is accomplished while rubbing of the clothes is obviated and injury to the fabric is thereby prevented.

It is not desired to limit the invention to the exact proportions as herein set forth, as the same may be modified, depending upon conditions.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. A washing and bleaching compound consisting of a mixture of perborate of sodium, borax and a salt (not alkaline).
